[0008] The head drive gear assembly includes a first connecting post and a head drive gear. The head drive gear is rotatably connected to one side wall of the mounting cavity. A first boss is formed on the end face of the head drive gear, and a right-angle gear ring is formed on the end face of the first boss. The right-angle gear ring of the first boss is adapted to the right-angle gear ring of a first convex ring. The first connecting post is rotatably connected to the middle of the mounting cavity. The upper end of the first connecting post extends out of the housing. A frustum is connected to the upper end of the first connecting post. An eccentric post is provided on the frustum. The eccentric post is located in a strip hole. A transverse gear is provided at the lower end of the first connecting post. The transverse gear meshes with the head drive gear.

[0009] Furthermore, a sliding hole is formed in the middle of the first boss, and the driven gear and the first boss are sleeved on the same shaft and slide together.

[0010] Furthermore, a second rotating shaft is provided inside the mounting cavity. The second rotating shaft is located between the transverse gear and the head drive gear. A transition gear is provided on the second rotating shaft, and the transition gear meshes with the transverse gear and the head drive gear.

[0011] Furthermore, the U-shaped sleeve includes two vertical plates and a horizontal plate, with the horizontal plate connected to the ends of the two vertical plates;

[0012] The hip drive gear set includes a hip drive wheel, which is rotatably connected to one side wall of the mounting cavity. A second boss is formed on the end face of the hip drive wheel, and a right-angle gear ring is formed on the end face of the second boss. The right-angle gear ring of the second boss is adapted to the right-angle gear ring of another first protruding ring. An extension shaft penetrating the two side walls of the housing is provided at both ends of the hip drive wheel and the second boss. The two ends of the extension shaft are respectively fixedly connected to the ends of two vertical plates. A return torsion spring is sleeved between one of the vertical plates and the extension shaft.

[0013] Furthermore, a second convex shaft is formed in the middle of the second boss, and the driven gear and the first convex ring are sleeved on the second convex shaft and slide.

[0014] Furthermore, mounting posts are formed at the upper ends of the two side walls of the housing, and the mounting post on either side is rotatably connected to the side wall of the housing;

[0015] The doll also includes an arm swinging component, which includes a turntable, a first connecting rod, and an extension plate. The extension plate is connected to the circumference of a mounting column that is rotatably connected to the housing. The turntable is rotatably connected to the side wall of the housing and located below the mounting column. One end of the first connecting rod is hinged to the end face of the extension plate, and the other end of the first connecting rod is eccentrically hinged to the end face of the turntable. The turntable and the second rotating shaft are connected by a column.

[0016] Furthermore, a stabilizing plate is provided in the middle of the mounting cavity, and the stabilizing plate has a through hole in the middle, through which the first connecting post passes. Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model controls the engagement of the active gear set and the head drive gear set by switching gear sets, thereby enabling the head mounting sleeve to move back and forth. By switching gear sets, the active gear set is controlled to engage with the hip drive gear set, causing the hip mounting swing kit (i.e., the U-shaped sleeve) to swing up and down.

[0018] 2. In this design, the driving gear rotates clockwise, thereby driving the driven gear to rotate counterclockwise. Since the driven gear has first convex rings on both end faces, and the surface of the first convex rings has right-angle gear rings facing opposite directions, when the driven gear rotates counterclockwise, the right-angle gear ring on the right side of the first convex ring makes planar contact with the right-angle gear ring on the first boss on the side of the head drive gear, thus driving the head drive gear to rotate. Meanwhile, the right-angle gear ring on the left side of the first convex ring makes inclined contact with the right-angle gear ring on the second boss on the side of the hip drive wheel. During rotation, due to the inclined plane, the driven gear moves towards the side of the head drive gear, thus achieving complete meshing between the right-angle gear ring on the first convex ring and the right-angle gear ring on the first boss. Conversely, the right-angle gear ring on the other side of the first convex ring disengages from the right-angle gear ring on the second boss. Similarly, when the driving gear rotates counterclockwise, it drives the driven gear to rotate clockwise, and the right-angle gear ring on the first convex ring meshes with the right-angle gear ring on the second boss.

[0028] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0029] like Figures 1-8 As shown, this embodiment provides a doll that can nod and shake its buttocks, including a shell 1, a head mounting sleeve 2, a buttocks mounting swing kit 3, a head drive gear set 4, a buttocks drive gear set 5, an active gear set 6, a switching gear set 7, and an arm swinging component 8.

[0030] The housing 1 has a mounting cavity 11 that extends through both sides of the housing 1. A stabilizing plate 12 is provided in the middle of the mounting cavity 11. The stabilizing plate 12 has a through hole in the middle. Protruding plates 13 are formed on both sides of the upper end of the housing 1. A limiting plate 14 is formed on the inward side of the upper end of the protruding plate 13. Mounting posts 15 are formed on the upper ends of the two side walls of the housing 1. The mounting post 15 on either side is rotatably connected to the side wall of the housing 1. The doll's arm kit is sleeved on the mounting post 15 by an internal wire.

[0031] The drive gear set 6 includes a first rotating shaft 61 and a drive gear 62. The first rotating shaft 61 is rotatably connected to the lower part of the mounting cavity 11. The drive gear 62 is fixedly disposed on the outer circumferential surface of the first rotating shaft 61 and located in the middle of the first rotating shaft 61. The housing 1 has a mounting groove, in which a motor 63 is disposed. The output end of the motor 63 is provided with a motor output gear 631, which is fixedly connected to the first rotating shaft 61.

[0032] The switching gear set 7 includes a driven gear 71, which is located on one side of the driving gear 62. The driven gear 71 meshes with the driving gear 62. The two end faces of the driven gear 71 form outwardly extending first convex rings 72. The surface of the first convex rings 72 forms right-angle gear rings. The right-angle gear rings on the two first convex rings 72 face opposite directions. By rotating the driving gear 62 forward or backward, the right-angle gear rings on the two first convex rings 72 are driven to mesh with the head drive gear set 4 or the hip drive gear set 5, respectively.

[0033] In another embodiment, the switching gear set 7 includes a driven gear 71 and a pushing component. The driven gear 71 has two end faces with outwardly extending first convex rings 72. The surface of the first convex rings 72 has right-angle gear rings. The right-angle gear rings on the two first convex rings 72 face opposite directions. The pushing component drives the right-angle gear rings on the two first convex rings 72 to mesh with the head drive gear set 4 or the hip drive gear set 5. The pushing component can be a pushing cylinder, such as a small electric cylinder. By setting two small electric cylinders on both sides of the driven gear 71, the small electric cylinders push out to realize the switching of the meshing objects of the first convex rings 71. The thickness of the driven gear 71 is greater than the thickness of the driving gear 62 to ensure that the driven gear 71 and the driving gear 62 remain meshed within the pushing range.

[0034] In summary, the switching gear set 7 only needs to be equipped with a driving component that can push the driven gear 71 to move left and right to achieve the switching gear set 7 function of this solution.

[0035] In this embodiment, the switching gear set 7 and the hip drive gear set 5 are arranged horizontally, so that the hip-mounted swing kit 3 can move up and down. Based on this principle, the switching gear set 7 and the hip drive gear set 5 can be arranged vertically to realize the left and right swing of the hip-mounted swing kit 3.

[0036] The head drive gear set 4 is used to drive the head mounting sleeve 2 to move back and forth. L-shaped pins are formed on both sides of the bottom of the head mounting sleeve 2. The lateral ends of the L-shaped pins extend outward and are inserted into the lower part of the limiting plate 14. A horizontally arranged strip hole 21 is formed at the bottom of the inner cavity of the head mounting sleeve 2. The head drive gear set 4 includes a first connecting post 41 and a head drive gear 42. The head drive gear 42 is rotatably connected to one side wall of the mounting cavity 11. A first boss 421 is formed on the end face of the head drive gear 42. A right-angle gear ring is formed on the end face of the first boss 421. The right-angle gear ring of the first boss 421 is adapted to the right-angle gear ring of one of its first convex rings 72.

[0037] Specifically, a sliding hole 4211 is formed in the middle of the first boss 421. The first connecting post 41 is rotatably connected to the middle of the mounting cavity 11. The upper end of the first connecting post 41 extends out of the housing 1 and passes through the through hole. The first connecting post 41 passes through the housing 1 and the through hole to achieve two-point limiting. A frustum 412 is connected to the upper end of the first connecting post 41. An eccentric post 4121 is provided on the frustum 412. The eccentric post 4121 is located in the strip hole 21. A transverse gear 411 is provided at the lower end of the first connecting post 41. The transverse gear 411 meshes with the head drive gear 42. Two second rotating shafts 16 are provided in the mounting cavity 11. The second rotating shafts 16 are located between the transverse gear 411 and the head drive gear 42. Transition gears 17 are provided on the second rotating shafts 16. The two transition gears 17 mesh. The upper transition gear 17 meshes with the transverse gear 411, and the lower transition gear 17 meshes with the head drive gear 42.

[0038] The hip drive gear set 5 is used to drive the hip mounting swing kit 3 to swing up and down. Specifically, the hip mounting swing kit 3 includes a U-shaped sleeve rod 31, the two ends of which are rotatably connected to the two side walls of the housing 1. The U-shaped sleeve rod 31 includes two vertical plates 312 and a horizontal plate 311, with the horizontal plate 311 connected to the ends of the two vertical plates 312. The hip drive gear set 5 includes a hip drive wheel 51, which is rotatably connected to one side wall of the mounting cavity 11. A second boss 511 is formed on the end face of the hip drive wheel 51, and a right-angle gear ring is formed on the end face of the second boss 511. The right-angle gear ring of the second boss 511 is adapted to the right-angle gear ring of another first convex ring 72. Specifically, an outwardly extending extension shaft 512 is formed on the end face of the hip drive wheel 51 and the second boss 511. The extension shaft 512 extends out of the outer side wall of the housing 1, and the ends of the extension shaft 512 are fixedly connected to the two vertical plates 312 respectively. Furthermore, the head drive gear 42, the first boss, and the driven gear 71 are mounted on the extension shaft 512. A reset torsion spring 314 is mounted between the extension shaft 512 and the fixed post 313, and the reset torsion spring 314 is used to control the reset of the vertical plate 312.

[0039] The arm swinging component 8 includes a turntable 81, a first connecting rod 82, and an extension plate 83. The extension plate 83 is connected to the circumference of the mounting post 15, which is rotatably connected to the housing 1. The turntable 81 is rotatably connected to the side wall of the housing 1 and located below the mounting post 15. One end of the first connecting rod 82 is hinged to the end face of the extension plate 83, and the other end of the first connecting rod 82 is eccentrically hinged to the end face of the turntable 81. The turntable 81 is connected to the second rotating shaft 16 located above it via a column.

[0040] Working principle: When the driving gear 62 rotates clockwise, it drives the driven gear 71 to rotate counterclockwise. Since the driven gear 71 has two end faces with first convex rings 72, each with a right-angled toothed ring facing opposite directions, one ring 72 is fitted to the first boss 421, and the other ring 72 is fitted to the second boss 511. When the driven gear 71 rotates counterclockwise, the right-angled toothed ring of the right-side first convex ring 72 makes planar contact with the right-angled toothed ring on the first boss 421 on one side of the head drive gear 42, thus driving the head drive gear 42 to rotate. The head drive gear 42 drives two transition gears 17 to rotate, and the transition gears 17 transmit the rotation to the transverse gear 411 of the first connecting column 41, causing the first connecting column 41 and the frustum 412 to rotate. The eccentric column 4121 is located inside the strip hole 21 of the head mounting sleeve 2, and the two eccentric columns at the lower end of the head mounting sleeve 2... The L-shaped pin 22 is locked between the pattern and the limiting plate 14, so that the head mounting sleeve 2 can only swing back and forth under the drive of the eccentric column 4121. At the same time, when the transition gear 17 rotates, the second rotating shaft 16 will also rotate, thereby driving the turntable 81 to rotate. With the cooperation of the first connecting rod 82 and the extension plate 83, the mounting column 15 realizes the back and forth swing (that is, the swing of the hand). Moreover, when the driving gear 62 rotates clockwise, the right-angle gear ring of the first convex ring 72 on the left side makes inclined contact with the right-angle gear ring on the second boss 511 on the side of the hip drive wheel 51. When rotating, due to the effect of the inclined surface, the driven gear 71 will be forced to move towards the head drive gear 42, thereby achieving complete meshing of the right-angle gear ring on the first convex ring 72 and the right-angle gear ring on the first boss 421, and disengaging the right-angle gear ring on the first convex ring 72 on the other side from the right-angle gear ring on the second boss 511.

[0041] Similarly, the driving gear 62 rotates counterclockwise, thereby driving the driven gear 71 to rotate clockwise. The right-angle gear ring on the first convex ring 72 meshes with the right-angle gear ring on the second protrusion 511, while the right-angle gear ring on the other first convex ring 72 disengages from the right-angle gear ring on the first protrusion 421. The rotation of the second protrusion 511 drives the hip drive wheel 51 to rotate together, thereby causing the vertical plate 312 adjacent to the hip drive wheel 51 to swing upward. The driving gear 62 stops rotating, and under the drive of the return torsion spring 314, the vertical plate 312 swings upward. By controlling the driving gear 62 to rotate counterclockwise intermittently, the hip shaking action is achieved.

[0042] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
